Citrix Client Drive Mapping

[Geoff]

I'm having a problem getting access to the USB sticks on my thin clients (These are all old PC's converted to thin clients with thinstation btw). The USB drive maps correctly to U: as I want however I get an 'access denied' errror when I attempt to open the drive up. This even happens as Administrator. I have checked:

Group Policy Settings
Terminal Server connection settings
Citrix Policy Settings
Citrix Server Settings

Any ideas?

IIRC you might need to add the following line to the webica.ini file:

[Access]
GlobalSecurityAccess=405

This will give full access to client hardware.

You also need to check the access policy to make sure that you have allowed use of USB drives in the first place.

Another thing to check is that clients are passing through devices such as scanners - if not this might indicate that USB access is restricted somewhere.

[Geoff]

The webica.ini file only applies to win32 clients AFAIK. The client is a Linux machine.

I have allowed the use of client drives. On Linux, the mount point looks like a hard drive to citrix, so I've allowed it that way.

The drive is visible and mapped correctly in the citrix session (I can see the capacity and free space for example).

And do USB drives/scanners/etc. work on other clients?

[Geoff]

The only other clients I have are some HP Linux based terminals. They have the same problem. I'm going to install the windows client on my VMWare WinXP install and try that.

@Geoff: Which HP Linux client? You need to turn a setting on at these clients to make USB work anyway.

The easiest way to do this is add the following to /etc/hpoptions

ENABLE_USBSTORAGE=TRUE

[Geoff]

They are t5135's. I will check the USB settings on one of them tomorrow.

You mean the 'nearly a proper operating system' model

There is a tick box and a setting where you nominate a drive letter on these under one of the tabs of the admin pages.

I've installed the v10 client software on my WinXP vmware machine now. But I can't for the life of me find where to configure the remote drives. Any pointers?

[Geoff]

To answer my own question, it's automatic. I now get my floppy/CD/Hard Drive and USB key (if present) mapped to my citrix session. I can read/write to them fine.

Still got the access denied problem under Linux though.

[Geoff]

However, I don't get an access denied error on my Ubuntu desktop PC. Which means it's something in the thinstation build. I'm looking at you supermount. I suspect file/directory permissions.

[Geoff]

However, using the prebuilt thinstation ISO works fine. Thus, it must be something in paticular to do with the way I've configured/built my Thinstation image.

Off to the thinstation mailing list I think.

Told you

There will be some random module that is required. Perhaps unload the modules that you deem unnecessary on the ISO image one at a time until it stops working?

ever get this working?

@griphter
We've done this recently on thinstation.
roughly went like this:
1) make sure thinstation OS can read/mount disk
- check /var/log/messages for USB and /mnt/usbdevices for mounts
2) make sure Citrix client reads the disk
- these lines in the thinstation.conf.network

ICA_WFCLIENT_CDMALLOWED=On
ICA_WFCLIENT_DRIVEPATHU=/mnt/usbdevice
ICA_WFCLIENT_DRIVEENABLEDU=Yes
ICA_WFCLIENT_DRIVEREADACCESSU=0
ICA_WFCLIENT_DRIVEWRITEACCESSU=0

3) make sure the citrix policies can allow USB drive mapping
4) make sure windows group policies are not preventing mapping permissions
5) ???
6) set mappings through GPO to map as U:\ drive
